policy set --snapshot-interval=inherit not working

[dimejo]

Inheritance of the --snapshot-interval parameter works when it is defined in the global policy and not defined in the path policy. If the path policy sets a scheduling it is not possible to unset it by running kopia policy set --snapshot-interval=inherit.

kopia policy set --snapshot-interval=inherit user@host:/path/to/backup
kopia: error: time: invalid duration "inherit", try --help

It is however possible to force inheritance by manually editing the policy and removing the entry in the scheduling section.
kopia policy edit user@host:/path/to/backup
"scheduling": {},
